Pricing

Here are details of the cloud plans and on-premises products that we offer. All prices are in US$, and include tax based upon your location if applicable.

Cloud plans On-premises installation

Cloud plans

Our cloud plans allow you to get started with Structurizr quickly, without needing to host and update software on your own servers. You can read about how and where data is stored, and our privacy policy explains how we use your data. The paid plans are aimed at teams and provide access to the full feature set, with a varying number of workspaces, on a monthly subscription basis. These are also available at a discounted rate for one year (this is a non-renewing payment rather than an annual subscription).

Per team pricing, not per user

Unlike typical software modelling and documentation tools, where the pricing is hundreds or thousands of dollars "per user", Structurizr's pricing is designed to be "per team", for whatever your own definition of a "team" is.

"Per user" licensing tends to result in a common anti-pattern where a small number of people end up being responsible for updating diagrams, with the resulting diagrams often being manually exported to static images for inclusion in documentation or wiki pages. We think that good software architecture diagrams and documentation should be accessible by everybody on the team, rather than just those lucky few individuals who are fortunate enough to have licenses for tooling.

Workspaces owned by a paid customer can be shared with free users, so you only need to purchase one subscription/annual plan for your team.

Need more workspaces?

Plans with more than 50 workspaces are available for annual purchase; please contact us for pricing.

The "Team Plan" is now known as the "Cloud Plan". The "Personal", "Standard" and "Enterprise" plans have been discontinued and are no longer available for purchase. Existing active monthly subscriptions and annual upgrades are unaffected.

On-premises installation

We also have a standalone version of Structurizr that can be run locally on your own servers, providing all of the major features needed to visualise, document and explore your software architecture. The on-premises installation is available as a perpetual license with support and updates included for one year.

The on-premises installation is available to purchase via invoice only. Please contact help@structurizr.com with your name and company details if you would like to purchase the on-premises installation.

Frequently asked questions

Is there a free plan and trial?

Yes, the Free Plan is aimed at individuals, and provides a single workspace with the basic features needed to create software architecture diagrams and documentation. After signing up for our Free Plan, if desired, you can activate a free 14 day trial by using the link on your dashboard. This trial allows you to create up to 3 workspaces and unlocks all of the available features, including the on-premises installation. This is obligation free and no payment details are required. After the trial period, your account will revert back to the Free Plan.

Do you manage credit card details yourself?

No, we use Braintree Payments (a PayPal company).

Which credit cards do you accept?

We accept Visa, Mastercard and American Express.

Refunds (annual cloud plans only; excludes the on-premises installation)

If you're not happy for any reason, we'll give you a full refund within one calendar month from the date that you purchased your annual cloud plan. After this time, no refunds will be given. Contact help@structurizr.com from the e-mail address that you signed up with.

Cancelling a monthly subscription

To cancel a monthly subscription, simply use the link on your dashboard. No refunds are given on monthly subscriptions.

Changing a monthly subscription

There is currently no way to change a monthly subscription. If you'd like to move to a larger cloud plan, you will need to cancel your current subscription using the link on your dashboard, and re-subscribe when your current month expires. If you'd like immediate access to the larger plan, please contact help@structurizr.com after you've cancelled your current subscription.

Updating credit card details

We do not have access to your credit card details, so it is not possible to change these to reflect a new credit card number or revised expiry date. To change your credit card details, please cancel your current monthly subscription using the link on your dashboard, and follow the instructions in the confirmation e-mail about how to resubscribe to the same plan.

Failed payments

If a monthly subscription payment fails for any reason, your subscription will be cancelled. In this situation, we will send you an e-mail with instructions about how to resubscribe to the same plan with alternative payment details.

Invoicing (annual cloud plans and on-premises licenses only)

Please contact help@structurizr.com if you would like to purchase an annual Cloud Plan or On-Premises installation via an invoice; including your business name, address and any purchase order details. Due to the EU VAT place of supply rules, EU registered businesses must also include their EU tax number to avoid being charged VAT at the local rate.

For Cloud Plans, an additional $50 administration fee will be added for purchases that are not made via the online payment process.

EU tax for b2c transactions

Individuals in the EU are subject to tax at their local rate for the supply of digital services via the Internet (see Electronically supplied services for more details). EU registered businesses can enter their EU VAT number during the purchase process to have VAT deducted.

Resellers

Please note that all sales are direct only; we do not work with resellers.

Do you support open source projects and non-profit organisations?

Yes, free cloud-based plans are available for open source projects, academic establishments, and other non-profit organisations.
